'To all whom it may concern halve invented certain new and useful Improvements -in` Automatic Talking-Machines, of which the following is declared to bea full, clear, and exact description.

The invention relates to talking or soundreproducing machines and seeks to provide, preferably in machines of the disk record type, automatic mechanism for changing the records or disks and for shifting the soundbox or reproducer into position Vto commenc the reproduction ofthe record.

Further objects'are to provide mechanism for automatically changin the sound-box needle or stylus; to provi e means for automatically bringing a number of disks or records into operation, together with means whereby any particular record may be selected as desired by the user of the machine; to provide operatin means for the automatic mechanism t at. may be coin-controlled so that all of the parts of the machine may be arranged within a suitable inclosing casing and to provide means for `preventing the operation of thef automatic mechanism when the talking machine is reproducin a record.

With t ese and other objects in view, the invention consists in the features of construction, and combinations of parts hereinafter set forth, illustratedin the accompanyy ing'drawings and more particularly pointed oli-tain the appended claims.

lIn the drawings, Figure 1 is a front elevation of the improved machine as arranged within an inclosing casing. Fi 2 is a plan view thereof with the casing an other parts shown in section on the line 2--2 of Figs. 1 and 3. Fig. 3 is a rear elevation of the operating mechanism with the casin in section. y Fig. 4 is an enlarged'detail p an"` view of4 a portion of the, operating mechanism, certain parts bein in section on theline 4 -4 of Fig. 3.

Fi 7 is a side elevation4 of the' arts shown in gs. 5 4and-6 and with the machine'rame in section: Fig. 8 is a side elevation -of the sound-box or reproducer,"its supportingartial front arms and means for controlling its shift. F1g.19 is a detail elevation showing the side of the sound-box opposite to that shown in 8 and with certain parts in section on line 9 9 of Fig. 10. Fig. 10 is a front view of the sound-box with parts in section on the line 10-10 of Fig. 9. Fig. llis a face view of the cam plate that controls the shift of the sound-box, parts being shown in section on line 11-11 of Fig. 8. Fig. 12 is a front view of the sound-box and its supporting arm. Fig. 13 isa horizontal section through the needle carrier or magazine takenzenthe line 13-13 of Fig. 14. Fig. 14 is a front elevation of the lower portion of the needle magazine with certain parts shown in section on the line 14-14 of Fi 13.

To prevent improper inter erence with the machine and its operating mechanism, all parts are inclosed within a suitable upright casing A. that is rectangular in section, as shown in Fig. 2, and that is provided with a removable back portion a to afford access to the mechanism. The front and sidesof the casing may be provided with glazed openings 1 through which the operation of the mechanism may be viewed. The casing is mounted on feet 2 and the amplifying horn B on the machine extends throu h the top of the casing at one side thereof, with its bell or mouth b opening at the front. The operating -parts are carried within the casing upon a frame consisting of a number of upright 'bars 3 that are connected by a number of horizontallongitudinally extending bars 4 (see Fig. 3) and by horizontal cross bars 5 (see Fig. 2). These bars are of meta-l and are securely connected to form a ri 'd frame that is mounted within the casinl upon a pair of supports 6 (see Fig. 3) an held therein against movement by lugs 7 on the side Walls of the casing. The lugs 7 are preferably removably held in place by crewase that by removing the back of the casing'and detaching the lugs, the frame wonk' and parts carrie thereby may be taken out forrepairs an the like.

l; stated, the machine is' particularly for use in connection with flat disk leftdla'h and'or this urpose lthe horizontal, tal'bleitnrn-table for the disk records `(se'elliga2,e', 5 and?) is carried u on the n 'efnd 'of a short vertical "sha 8 in tlie'per, central portionof the frame. The urn-table shaft and- 'its operatingv mechanism is mounted u on a supplemental rigid frame 9 (see Fig. 7 that is secured to the upper ends of the central uprights 3 of the main frame. The lower conical end of the turn-table shaft 8 is stepped within a suitable bearingufpon an upright lug 10 of the supplemental rame 9, and its upper end projects through a cross bar of the frame and supports the turn-table C. The turn-table is driven preferably b a spring motor, the casing D of which is xed to the rear cross bar of the frame 9. A coiled sp'rin d within the casin is fastened at one end thereto and at its ot er end to a horizontal shaft 11 that extends through the casing and is journaled in the front and rear cross bars of the frame 9. A gear 12 loose on shaft 11 (see Fi 5 and 7), is provided with a springhe d pawl 13 arran ed to enga e a ratchet wheel 14 that is fixeA t6 the sha t so as to be driven thereby when the spring rotates the shaft 11 in one direction but permitting the spring to be wound up by rotating the shaft in the opposite direction without moving the gear 12. This gear meshes with the pinion 15(see Figs. 3 and 7) that is carried upon a short, horizontal shaft 16 journaled in the supplemental frame 9 and arran ed parallel with the motor shaft 11. A beve ed gear 17 on the forward end of the shaft 16, meshes with the beveled pinion 18 on the lower end of the turn-table shaft 8. The turn-table is thus driven from the spring motor by the train of gearing described.

The amplifying horn B within the top of the casing A extends from the center of the casing outwardly toward one side thereof.. At its outer end the horn is provided with an upturned elbow that projects through the top of the casing and connects with the bell or mouth piece b. At its inner end the horn is provided with a downturned ..oovv portion that is provided with a. ring 19 having an off-set 20 (see Fi s. 2 and S) by which it is secured to one o the uprights 3 of the frame. The horizontal ring 19 is provided on opposite sides with a pair of horizontal slots 21 within which set pins 22 that are fixed to the outer upturned end or elbow portion of a hollow reproducer arm 23. The pins 22 are preferably prof vided with anti-friction rollers 24 that it within the slots 21. At its inner end the arm 23 is provided with a horizontally turned elbow portion that carries an upright sound-box 25. holder 26 is connected to the sound-box by two screws 27 that extend loosely through ears 28 on the stylus holder and are threaded into the sound-box. Springs 29 are coiled about the outer ends of the screws and interposed between the heads 4thereof and the ears 28 yieldingly hold the stylus support in position. The stylus support or holder 26 is provided with an arm A needle or stylusV 1,1s4,eos

30 that is connected to the diaphragm 31 of the sound-box. At its outer end the hollow reproducer arm 23 is provided beyond its connection with the horn, with a rod 32 eX- tending in line with the arm and carrying a counter-weight 34, which may, if desired,A

be adjustably mounted on the rod 32. The sound-box and reproducer arm are moved over the surface ofthe disk records on the turn-table C in the usual manner by the engagement of a needle or stylus thereof with Vthe spiral record groove of the disk. Durpressure on the disk. At one end the ori-A zontal slots 21 of the ring 19 are open so that the re roducer arm may be readily connected an disconnected from the horn. It will be understood in the ordinary travel of the arm, the pins 22 will not come opposite the open ends of the slots. As indicated in Figs. 8 and 12, that portion of the elbow on the outer end of the arm 23 that projects Within the ring 19 in the horn, is in the form of a head having a surface which constitutes a, segment of a sphere so that a sound-tightl joint between the arm and horn will be maintained in spite of the universal movement of the arm with reference to the ring.

The speed of the turn-table and the disk record supported thereby is controlled by a suitable centrifugal governor that comprises, in the form shown, weights E (see Fig. 7,) mounted centrally on bowed springs that are fixed at their ends to lower and upper collars 36 and 37 that are mounted upon a vertical governor shaft c. This shaft is journaled at its upper and lower ends in the supplemental motor frame 9 and the upper end of the shaft is provided with a pinion 38 meshing with a gear 39 on the short turntable shaft 8. The collars 36 and 37 have expanded friction disk portions and the lower collar 36 is fixed to the Shaft While the upper one is loosely mounted thereon. An arm 40 is pivoted at its forward end to the end of a lug 41 on the forward part of the motor frame 9. The rear end of this frame is forked (see F ig. 5) and provided with pads of felt or like material arranged to engage the friction disk or collar 37. A screw 42 threaded through the lug 41 engages the arm or lever 40 and adjusts its position to thereby vary the speed of the turn-table. In operation, the weights E iiy outwardly and draw the disk 3:? down upon the end of the arm so as check the rotation of the turn-table C and compel it to rotate at a uniform rate of speed. l

' The motor shaft 11 is provided on its forward end with a small sprocket wheel 43 (see Figs. 3, 5 and 7). A chain 44 passes over this wheel and over a large sprocket wheel 45 mounted on a shaft F. Shaft F is journaled in suitable bearings on the horizontal bars 4 at the lower end of the frame, and its forward end pro}ects through the front of the casing A and is provided with a crank handle f (see Fig. 1). .The sprocket chain 44 (see Fig. 7) is provided at one point with a horizontal projecting stud 46 that is arranged to engage and llft an arm or lever 47 that is pivotally connected by `a stud 48 to the motor frame 9 and projects laterally beneath the governor arm 40 so that the latter is lifted with the arm 47 and its inner end pressed firmly into engagement with the governor disk 37 to stop the operation of the turn-table C. The pin or stud 46 on the chain 45 is so positioned that it will engage the arm 47 to lift it and the governor arm 40 and thereby stop the rotation of the disk C, after the latter has lbeen`driven for a su'licient length of time to reproduce the sound record thereon. It will be understood that the sprocket wheels 43 and`45 and sprocket chain 44 are moved in one direction to wind up the motor spring d, and are driven by the spring in the opposite direction, while the turn-table is rotated to reproduce a record thereon. By this arrangement when the large wheel 45 is turned in one direction to wind up the motor, the pin 46 onthe chain 44 will be moved away from the arm 47 and the inner end of the governor arm 40 will move away from the disk 37 so that the turn-table may rotate. During the rotation of the turntable, the chain is driven in the opposite direction and as soon as the pin 46 thereon engages and lifts arms 47 and 40, the operation of the motor and turn-table will be arrested. Vhen the pin 46, moves from under the arm 47 the latter is lowered until a forwardly projecting oset stud 49 thereon (see Figs. 6 and 7) comes into engagement with the front bar of the motor frame 9. Although the large sprocket Wheel 45 thus rotates in opposite directions, the winding shaft F rotates only in one direction toA and the Wheel 45 is therefore loosely mounted on the shaft. A ratchet wheel 50 (see Fig. 5) fixed to the shaft F in front of the sprocket wheel 45, carries a pivoted pawl or dog 51. A spring 52 connected to the ratchet disk and to the pawl is arranged to shift and hold the latter in line with the lug 53 fixed to and projecting forwardly from one of the arms of the sprocket wheel 45. The tail of the pawl 51 extends opposite a notch 54 in the periphery of the ratchet disk 50, and, in the normal position -of the ratchet wheel or disk 50, a trip pawl or dog 55 projects within the notch 54. This' pawl is pivotally mounted on the frame and a spring 56 extends between the frame and a lug 57 on the pawl and tends to project it Within the slot 54. The end of the trip paw] 55 is wide enough to engage the notch 54 in the ratchet disk 50 and to also engage 4the tail of the pawl 51, and spring 56 of tle trip pawl or dog 55 is `stronger than the spring 52 of the pawl or dog 51 so that the latter is normally held in the position shown in Fig. 5,- against the tension of its spring 52 and out of line with the lug 53 on the sprocket wheel 45. When the pawl 55 is in the notch 54 the ratchet disk 50, shaft F and winding handle f are locked. Suitable means .are provided for lifting the dog or p awl 55, and' when this 1s done shaft F is unlocked and spring 52 moves the dog or pawlv 51 into line with the lug 53 on the sprocket wheel'45. Then by turning the handle, the dog 51 on the ratchet wheel may be brought into engagement with 'the lug 53 to turn the sprocket Wheel and wind up the spring motor. The parts are so positioned that, when dog 51 engages the lug 53 the locking pawl 55 will engage the teeth of the ratchet 50 and Will prevent the return movement thereof. It will also prevent the return movement of the sprocket Wheel 45 and of themotor shaft 11 until shaft F and ratchet disk 50 have been moved through a complete revolution and brought the notch 54 of the disk again beneath the end of the pawl 55. When this occurs, dog 55 will drop into the notch 54, lock the ratchet wheel and shaft F and will engage the tail of the pawl 51 to trip it out of engagement with the lug 53 on the sprocket wheel 45. The latter wheel and the motorshaft are then free to be driven by the spring motorin the opposite direction as disk C is rotated in reproducing the record thereon. By this arrangement the user of the machine is compelled to completely wind up the motor before it can operate to rotate the turn-table and at thcsame time he is prevented from overwinding the motor. The end of a stiff leaf spring 58 fixed to the frame is arranged to engage a pin 59 on the face of the ratchet disk as it approaches the end of a single revolution, and as the pin snaps by the end of the spring 58 the movement of the ratchet wheel is checked so that the locking disk or pawl 55 will invariably drop into the notch y54 of the ratchet wheel to check its forward movement and lock it after it has made a single revolution. Pawl or dog 55 is preferably shifted out of the notch 54 by a coincontrolled mechanism comprising aV pair of levers or arms 60 and 61 that are pivotally mounted on the frame on opposite sides ofy a suitable coin chute 62 that leads from a slot 63 (see Fig. 1) in the front of the machine casing. The lever or arm 61 `is provided on its end with an off-set lug 64 that projects through a transverse slot in the coin chute. A spring 65 connected to the arm normally holds the lug 64 in position to engage and arrest the inserted coin as indicated in dotted lines in Fig. 5. The lever or arm 60 is provided on its end With an off-set lug 66 that projects through a transverse slot in the coin chute and is normally held in a position above the coin when the latter is arrested by the lug 64 on the arm 61. A lever or arm 67 pivoted between its ends to the frame below the pivot of the arm 60 is connected at one end to the arm 60 by a coiled spring 68. A link 69 pivoted to the arm 60 is provided with a V-shaped end arranged to engage and rock within a corresponding y shaped bearing in the edge of the arm 6 and 67 properly spaced apart and spring 68 holds the arm or lever 67 into engagement with the end of the link 69. The opposite end of the arm or lever 67 is provided with a cam portion 70 that is normally arranged adjacent a pin 71 on the ratchet disk 50. A projecting arm 72 on the pawl 55 is connected by a link or rod 73 to the lower end of the arm or lever 61.

It will be noted that the notch 54 of the ratchet disk 50 is somewhat larger than the end of the locking pawl 55 so that a sli ht initial movement may be given to the rato iet wheel by turnin the handle f of the shaft F. By this slight initial movement the pin 71 on the ratchet disk will press upon the cam portion 70 of the arm or lever 67 and turn the latter together with the arm or lever 60. If a coin has been inserted and arrested between lugs 64 and 66 on the levers 61 and 60, this movement of the lever 6() will shift the arm 61 so that the latter, through the medium of the. connecting rod or link 73, will lift lookin awl 55 from the notch 54 of the ratchet is so as to permit the continued forward movement of the shaft F. As the ratchet disk 50 is turned, a segmental ledge 74 thereon will be brought into engagement with the end of the arm 67 so that the parts actuated thereby will be held in shifted position until the pawl 55 is brought into engagement with the teeth of the ratchet disk 50. The lugs 66 and 64 on the levers 60 and 61 are so positioned that, during the movement described, the coin will be pushed past the lug 64 down into the casing of the machine. By providing a yielding spring connection 68 between the levers 67 and 60, it is impossible to break the parts should the coin become stuck in the chute.

The lever 67 is connected by a link or rod 75 anda coiled spring 76 tothe lug49 on vlug 64 on the arm 61.

Link 69 holds the arms 60 the end of the lever or arm 47. In the normal stationary osition of the parts as stated, this arm 1s upheld by the pin 46 on the chain 44 and through the medium of the sprin 76 and rod 75 the levers 67 and 60 are a so upheld with the end of the lever 67 in engagement with the pin 71 on the ratchet disk 50 and with the lug 66 on the lever 60 in its uppermost position indicated in the drawings. When the motor is wound up, pin 46 is moved from beneath arm 47 so that the latter drops down until the lug 49 thereon engages one of the cross bars of the frame. This also lowers the levers or arms 60 and 67 so that the lng 66 on the lever 60 is positioned in the center of the coin chute, and it is possible for the coin to drop in place between the lug 66 and the By this arrangement, it is impossible to release the winding mechanism until the motor has operated a. sulicient length of time to reproduce the entire record on the turn-table, but when the pin 46 again engages the arm 47 to arrest the motor, as described, lever arms 60 and 67 will be lifted and lug 66 on arm 60 moved back to its normal osition indicated so that the winding mec anism may be again released.

The disk records G are preferably carried by two magazines or holders arranged on opposite sides of the `turn-table C. In the form shown, each magazine or holder (see Figs. 2, 3 and 5) comprises a frame H mounted to slide on a pair of vertical rods 77 that are fixed at their ends to the metal frame work of the machine. Each holder frame H is provided with a vertical series of inwardly projecting horizontal rods` h that are arranged in pairs and upon which the separate disk records G are supported. The disk records are provided with the usual center openings and through tne central openings or holes of the set of disks on each holder or magazine, extends a pair of lixed vertical pins 78 and 79. The lowermost pin is fixed to a cross piece 80 of the machine frame and the uppermost pin is connected to a cross piece 81. The adyacent ends of these pins are Vspaced apart as shown, at a point in line with the turntable C. The ins 78 and 79 prevent the displacement o all of the records G from the holder or magazine, except the record that is opposite the space between the ends of the pins and opposite the turn-table C. The u permost pin 79 of each pair is however see Fig. 5) threaded into the cross bar 81 and 1s provided with a cross pin or handle 82 by which it may be unscrewed and removed from place so that when the back of the machine is open the disk records ma be changed as desired.

Syuitable means are provided for shifting the holders or magazines to bring any one disk opposite the space between the pins 78 A Such means preferably comprises a pair of magazines may be raised an arms J (see Figs. 3, 4 and 6) that are pivotally mounted at heir inner ends on a stud 83 fixed to a supp emental motor frame 84 that is suitably connected to the main frame beneath the main motor frame 9. The arms J extend in opposite directions from the stud 83 and are provided on their ends with rollers j that engage inwardly, projecting arms 85ifixed to the lower ends yf the magazine or holder frames H. Each arm is provided with a Abeveled pawl 86 that engages a stepped heartshaped, shifter cam K. The cams K are `mounted upon` a pair of horizontal shafts k that are suitably journaled in the supplemental Ymotor frame 84 and the .forward ends thereof project through the front of the machine casing and are provided with turning knobs 87, as shown in Fig. 1. `The arms J and record magazines or holders are supported in normal position `by the eams K. By rotatin the cams the lowered step the records opposite the arm J is guided between j fixed to the frame (see by-'st`ep to brin turn-tabl? `.Eac a a1r o pins lNiggas. 3 and 4).

The magazines are eachprovided with a pointer 88 (see Figs. l and 2) that coperates with a printed or written list within a frame 89 that is fixed to the machine frame. The list of course, contains the namesv of the several records of the adjacent magazine or holder and are arranged in corresponding proper Aorder so that the user of the machine may bring the desired record or disk into position at the space between the holding pins 78 and 79 and opposite the turn-table C'. The lists within the frames 89 and the ends of the pointers 88 are visible as shown in Fig. 1, through the front glazed opening in the upper part of the machine casmg. i

Each record magazine or holder is preferably counter-balanced by a Weight L (see Fig. 3) connected to the lower end of a wire cord 90 that extends over a guide pulley 91 at the top of the machine frame, and is connected at its other end to a lug 92 on the upper end of the magazine or holder frame The counter-weights L are preferably arranged within guide sleeves or tubes Z that are fixed to the frame. The disk. records are transferred to and from the holders or magazines by a reciprocating shifter or carriage M that is mounted to slide back and forth in the plane of the turn-table C (see Figs. 2, 3, 5 and 7). The shifter or carriage comprises a central brace bar m and side bars m lixed to the end of the central brace piece, as most clearly shown 1n Fig. 2. The carriage or shifter is mounted to Slide (ses Figs. 45 and 7) on rollers 93 mounted on two of the horizontal bars 4 at the front and rear of the frame. Pins 94 (see Fig. 2) fixed to the vertical bars at the front and rear of the frame, are arranged to project over the side bars m of the carriage to prevent the displacement thereof. ,A pair of arms 95 (see Figs. 2 and 7.) ivoted to the horizontal frame bars 4 at t le front and rear of the frame, carry rollers 96 that are yieldingly pressed by springs 97 connected to the arms into engagement with the upper edges of the side bars m of the carriage or shifter. The ends of the side bars m of the shifter or carriage are bent inwardly (see Figs. 2 and 7) to engage the record disks G and the carriage is of such length that it will engage the disk upon the central turn-table and a disk upon one of the holders or magazines, the disk on the turn-table .being-located between thecentral bar m and one end of the carriage, while the disk on the holder is between the central bar m and the other end of the carriage. When the carriage or shifter is moved from one extreme position to the other, it will shift the record on the turntable into one holder and move one of the disks on the. other-holder on to the turntable. For example, if the shifter is moved from its left hand position shown in Fig. 2 toward the right, the disk on the turn-table will be moved into the right hand holder or magazine and the disk record on the left hand holder that is opposite the turn-table and between the left hand pins 79 and 78, will be shifted on to the turn-table. The end portions of the carriage or shifter do not 1n its movement `ass over the turntable C, but the centra portion m thereof, which passes over the turn-table from one side to the other as the carriage is shifted, is arranged to just clear the turn-table but to enga e the edge of the disk thereon. To insure t at this central bar m shall e gage the edge of the disk, it is rovided with upwardly projecting incline ribs 98 (see Fig.

he disk upon the turn-table is accurately centered thereon as hereinafter described, and is thus held out of engagement with the sides of the carriage or shifter so that the latter does not interfere with the rotation thereof. The carriage moreover, does not interfere with the vertical shift of the magazine holders or carriers. In the drawings, the carriage or shifter is shown as in its left hand position so that it securely holds the disk thereon that is between the pins 78 and 79 against displacement, butthis holder can be shifted vertically to bring any one of the disks thereon into position be/ tween the arms or side bars of the carriage. The adjacent ends of the pins 78 and 79 are pointed, as shown, so that they may accurately engage the central openings of the disks as the disk holders are shifted. The

. the roller 96 that engage the upper edges of the side bars m of the carriage or disk shifter arelocated in line with the center of the tum-table C and that the rollers 93 that engage he .lower edges of the side bars m. are positioned at equal distances on opposite sides of the rollers 96 so that the end of the carriage that is innermost and adjacent the turn-table will be securely held against vertical shift. Y

The central portion m of the carriage is provided at its rear end with a horizontal pin or roller 99 fixed to a lug 100 depending therefrom. The upper forked end of a shifter arm N engages the pin or roller 9.9l (see Fig. 2). At its lower end arm N Y1a connected by a pivot bolt or stud 101 to the lower portion of the machine frame. The shifter arm N is driven from a short shaft 102.7that is journaled (see Figs. 3, 4, 6 and 7), in the supplemental motor frame 84. y.At its rear end the shaft is provided with a erankarm 103 that carries a pin 104 projecting within a cam slot n, in .the shifter arm N (see Fig. 3). At each operation of the machine the shaft 102 is given a halt` revolution and o crates to throw the shifterV armfrom one side to the other. The lower portion of the cam slot nis loop-shaped and divided by a rib 105, while the upper por tion of the slot is inclined. When looking at the machine from the rear, as shown in Fig. 5, the pin 10aL moves through the lower part of the slot. in moving the shifter arm from right to left and through the upper part of the cam slot in moving the arm from left to right. By the peculiar arrangementl of the cam slot, the carriage is started and brought to rest slowly. and easily and without shock or jar. Pin 104 is preferably provided with a roller that sets within the cam slot n.

A drum 0 (see 6 andf?) is loosely mounted on the front end of the'short sha Y 102. A steel tape p passes over, the drum and is fixed thereto at one end.v The other endv of the tape is secured to the free end of a shift lever P that is pivotally mounted on a stud 106 at one side of the lower portion of the machine frame. f-'Theshiffer arm P vextends over the 'shaft F and is providedwith a pin 107 that engages `a spiral cam 10,8 fixed to the shaft;

heavy springl "p isfi also lifts the dog s' out of't connected to the arm and tothe bottom of the inclosing casn and holdsthe pin'107 in'l engagement with t e cam 108. P1n107 is preferably provided with an anti-friction roller. Drum O is provided a't'its rear with a ratchet 109 arranged to engage a swings downwardly the dog that is fixed to the shaft 1702. Gear 111 (seev the rear end of a short shaft 113 that is journaled in the supplemental frame 84. A gear 114 on the frontend of the shaft 113 meshes with a pinion 115 on a short shaft r that is suitably journaled in the supplemental frame 84 and carries a governing fan R.v Fan R is normally engaged by a horizontal pin s that is fixed to and projects horizontall and forwardly from a bar S that is hel in vertical position by screws 116 (see Figs. 6 and 7 passing through vertical slots therein. Bar S may thus move vertically to an extent limited by the length of the slots. A coiled spring117 connected to the bar normally holds it inlowermost position with 4the -pin s thereon in engagement with the governor fan R. Bar S constitutes a stop device for controlling the operation` of the shaft 102 that operates the carria eshifter \N. The upper end of the bar is o -set rear- ,wardly' (see Fig. 7) and carries a pivoted dog s', the upper end of which is connected to .the bar S -by a coiled spring 118. The

ear 111 is provided on one face with a pr0- )ecting rib 119 of substantially circular form (see Fig. 6). This rib is provided at underv tension. "l" e-lowerend'o' 'the stop deviceorfbar S is turned rearwardly and projects in line with the path of movement" of the'arlnv P. l

so as'tfprevent the pin a thereon' from dropspring p as soon as the pin 107 thereon clears the shoulder of the spiral cam 108 on the shaft F. i This is effected just as the winding shaft F reaches the end of its revolution. Motor spring p' then draws down arm P and through the strap drum O, ratchet 109 and pawl 110 turns t e shaft 102 so that the latter moves the carriage shifter arm N and the carriage or record shifter is then operated to remove the record on the turn-table and place another record thereon. At the end of a halfrevolution of the shaft 102 which, as stated, is sufficient to move the carriage or record shifter from one side to the other, the do s on the stop bar S is drawn down by t e spring 117 of the stop bar S into the other notch 120 of the rib 119, and the pin s engages the governor fan R so that the shaft 102 and parts operated thereby, are arrested. The rib 119 is provided just in front of the notches 120 (see Fig. 6) with depressed portions 121 in advance of the notches 120 to lower the dog s' and bar S slightly before dog s drops into the notches. By this arrangement, the motor shaft 102 that operates the carriage or record shifter, is brought into operation and automatically arrested after it has com pleted a half revolution. The fan governor compels the even uniform operation of the shaft 102 under the iniuence of the motor spring p', and as stated the cam slotrwl and shifter arm N is so shaped that the record shifter and records are brought to rest slowl and without shock or 'ar.

It 1s desirable to prevent t e operation of the turn-table C until after the record shifter has completed its movement. To effect this, the stop bar S is provided on its end with a laterally projecting spring strip 122 that carries a friction button 123 covered with felt or like material. As stnted,the stop bar S is held in uppermost position during the movement of the record shifter since the dog s thereon rides upon the rib 119. When in this uppermost position, the friction button 123 engages the disk 36 on the lower end of the governor shaft E and thus prevents the operation of the turn-table motor until after the record shifter has completed its movement.

It will be noted that the records are shifted by the carriage onto the turn-table alternately from the record holders or magazines on opposite sides thereof, and that when a record is shifted from one of the holders, the record on the turn-table is moved back into the other holder. When the carriage is shifted fromleft to right,'a record in the left hand holder is moved onto the table and the record on the table is moved back into the right hand holder and when the carriage is shifted from right to left, a disk on the right hand holder is moved on the table and the disk on the table iS moved into the left hand holder. Thus in both positions of the carriage one of the magazines is `full of records while one record has been removed from the other magazine. It is necessary to prevent the vertical movement of the magazine from which a record has been removed, so that the record may be properly replaced therein by the movement of the carria e. It is also deslrable to provide means or automatically shifting the magazines vertically to bring the disks successively opposite the turn-table and into engagement with the carriage or shifter. For these pur oses, the shafts k that carry the cams K or vertically shifting the record magazines, are provlded on their rear ends with toothed looking wheels T (see Figs. 3 and 4). The spaces between the teeth of these wheels are semi-circular in outline and are arranged to be engaged by pins or rollers 124 on the outer ends of a pair of pawls or arms t. These arms are pivotally mounted at their inner adjacent ends upon an upright ortion or lug 125 of the supplemental rame 84. A leaf spring 126 fixed centrally to the lug 125, grages and depresses the pawls or arms en the pins or rollers 124 on the pawls t are down in the bottoms of the slots between the teeth of the wheels T, these wheels and the shafts la are locked so that the latter cannot be rotated to shift thelmagazines. The pawls t are provided with rearwardly pro- ]ecting pins 127 which' are arranged to be enga ed by a lu 128 on the forward side ofv the sifter arm When the 'pin on one of the arms is engaged by the lug 128, the arm will be held in such`position that the pin or roller thereon will only project slightly within one of the notches of theleorresponding wheel T, as shown -at the ri ht hand in Fig. 3. The ends of the teeth o the wheels T, are inclined and while, in its slightly raised position the small arm t will prevent the rotationl of the corresponding wheel in one direction, it will permit its rotation in the direction indicated by the arrow in Fig. 3, so that the user of the machine may move the magazine or holder at the right 1n Fig. 3 to bring any disk thereon into engagement with the disk shifter by turning the thumb button 87 of the corresponding shaft. The record holder or magazlne at the left of Fig. 3, from .which the record on the table has been removed, is looked against movement so that at the next operation of the machine it will be in pro er position to receive the record on the ta le. When the arm N is shifted to move a disk from the magazine at the right in Fig. 3 onto the table, the lu 128 on the arm will move out from beneat the pin 127 on the right hand locking pawl so that the latter will lock the operating shaft and magazine on that side, and it will stay locked until the record has been returned to the holder. The movement of the arm carries the disk on the table back into the magazine at the left in Fig. 3, and at the end of its movement glug 128 on the arm will engage the pin 127 of the left hand locking pawl t so as to release the shaft k and the magazine operated thereby on that side. In this way the magazines or holders on opposite sides of the turn-table are alternately locked and unlocked as the record shifter or carriage is moved. When the carriage is at either end of its movement, the magazine at that end is unlocked so that the user may select the next disk that is to be moved onto the table at the next operation of the machine. The magazine or holder at the opposite side of the machine is however locked until the disk that has been removed therefrom is returned by the movement of the disk shifter. It will also be noted that while the shifter arm and carriage are moving, both of the shafts lc are locked against movement and neither of the magazines can be shifted.

For automatically shiftin the magazines the crank arm 103 on the s aft 102 is provided at its end with a tooth t (see Fig. 3). The cam slot n in the arm N is so shaped that, as stated, the arm and carriage are brought to rest slowly. It is also so shaped that the arm N and carriage reach the end of their movement before the crank arm 103 reaches the end of its movement. So that as the arm 103 and shifter arm N move to one side of the machine, the lug 128 at the end of the'movement of the arm N first lifts the locking pawl t to release the wheel T and shaft lc on that side and subsequently the tooth t' on the arm 103 at the end of the movement of said arm is brought into engagement with one of the teeth of the wheel so that it and the shaft k is advanced one notch to move the corresponding magazine and shift another disk into engagement with the disk shifter and opposite the turn-table C. By this arrangement, if the shafts k are not turned by the users `of th'e machine, a different record will be placed on the turntable at each operation of the machine until all of the records have been successivel reproduced. This automatic operation however, does not prevent the user of the ma.- chine from selecting any record in the magazine that is unlocked;

The record on the turn-table C is held in proper osition thereon by a centering device V see Figs. 2 and-7) that has a conical roller on its lower end arran ed to extend throu h the central opening o the vdisk and into t e recess of the central, portion of the turn-table C. The centering device is car- I'ied upon the end of a forwardly extending, horizontal portion 129 of a' vertically reciprocating shifter-bar 'v Thls bar is mounted at the Yrear of the machine frame, its lower end being connected to the frame and guided by a screw 130 extending through a vertical slot therein. The upper end of the bar is arranged to slide through a U-shaped strap 131 fixed to one of the horizontal bars on the machine frame. The shifter V is raised and lowered to release and clamp the disks upon the turn-table by a spiral cam 132 (see Flgs. 3 and 4) that is mounted upon the rear end of a horizontal shaft 133 journaled in the machine frame. The inner end of the shaft is provided with a gear 134 meshing with the gear 111 on the motor shaft 102. As stated, motor shaft 102 is iven a half-revolution to operate the disk s ifter. Gear 134 is exactly one-half vthe size of gear 111 so. that it is given a complete revolu i l to first raise the centering device and s :lf-.ase the record on the turn-table, and then to permit the downward shift thereof to en age and hold the n ew disk that is placed lon the table. The lower end of the shifter rod is preferably V-shaped and sets within a. correspondin ly shaped notch in the cam 132 in the norma position of the parts so that the centeringr device is accurately held in its proper position. The shifter arm o also serves to move the reproducer arm to the outer periphery of the disk on the turn-table to commence the reproduction thereof and the shifter arm also operates the needle changing mechanism. For these purposes a se ental track-bar W (see Figs. 2 and 5), is pivotally connected at one end by a stud 135 to the frame of the machine o posite the center of the turn-table. The ot er end of the track-bar W is pivoted to a lug 136 on the side of the horizontal portion 129 of the shifter rod lv. The track-bar W is concentric with the center of motion of the hollow reproducer arm 23 and the latter is provided on its under side with a roller w (see Fig. 8) journaled between a pair of lu 137. In the normal, horizontal position o the trackbar W and with the needle of the reproducer arm resting upon the disk, the roller fw is above the track-bar W but out of engagement therewith. When the reproducer arm is in its innermost position the vertical shift of the rod v will raise the inner end of the track bar W and the latter will engage the roller fw and lift the reproducer arm. The track bar W is then in inclined position so that the reproducer arm may slide down the same until the roller w engages a lu 138 at the outer end of the track bar. light spring 139 (see Fig.; 5) on the track oar is arranged to en age the roller w whenthe latter hits the ug 138 to prevent any rebound of the reproducer arm.

The needle or stylus Y (see Figs. 8 to 12) is arranged within the bore of the hollow cylindrical holder 26. A clan-1p 140 is connected by a pivot screw 141 to a lug 142 on the rear face of the sound box. This clamp is pivoted toswing in a plane at right angles to the holder 26. A coiled spring 143 arranged in a socket in the end of the lug 142 engages the end of the clamp 140 and presses it through a transverse slot 'in the side of the cylindrical holder 26 into engagement with the needle or stylus Y to hold the latter firmly in place. -The inner end of the needle abuts against the shoulder 144 (see Fig. 10) at the inner end of the bore of the holder 26."

The sound box is providedwith a finger 145 that extends in line with the reproducer arm 23. After a record has been reproduced the sound box and arm 23 are brought to rest with the end of the finger 145 against the lower end of a'V-shaped cam plate 146 on abracket 147. This bracket (see Figs. 2 and 5) is arranged above the turn-table adjacent the central portion thereof. It is secured at its upper end and depends from the hori-n zontal plate portion 148 of a bracket 149 (see Figs. 5, 8?, 13 and 14). Bracket 149 is cast in one piece with the frame bar 150 that is suitably secured at its ends to the metal frame ofthe'machine. The bracket 147 is provided with a second V-shaped cam plate 151 arrangedadjacent and parallel to the cam plate146 so as to form a zigza cam slot or guide-way. Plate 1511 (see Fig. 11) is shorter than plate 146 so that the pin 145 may pass beneath it into engagement with the lower end of the plate 146. Bracket 147 is also provided at its lower end and at one side with a vertical trip cam 153 and with a hook-shaped abutment or stop 154. The cam 153 is so placed that when the sound box and reproducer arm are lifted by the shifter rod r and rail W, it will engage the tail of clamp 140 and shift it against the tension of its spring 1'43 to release-the nee e and to permit it to fall fromv the holder 6. This partial raised position of the sound boxis indica-ted by dotted lines in Fig. 11. When the reproducer arm and sound box are lifted, the end of the pin 145 will enter and pass through the V-shaped cam groove 152 and the reproducer arm and sound box willinot slide down the rail W to the outer periphery of the record on the turn-table until after the pin 145 has passed out' of the upper end of the slot. The end portion of the pin 145 that projects within the slot 152, is preferably provided with an anti-friction roller The stylus or needle magazine (see Figs. 1, 13 and 14) preferably comprises a circular series of vertical tubes 156 that are secured at their ends to and extend through a pair of upper andV lower ldisks 157 mounted on a central shaft 158. Shaft 158 isjournaled at' its ends in the arms of a Ushaped holder 159. This holder is arranged to set at its lower'end upon the plate portion 148 of the bracket 149'." This bracket` and the supporting frame; bar 150 therefor", is

(see Fig. 14), the ores of the tubes being of' suicient size to readily receive the nee. dles and permit the passage thereof through the' tubes, but are small enough to hold the needles in upright position, one on top of the other. The lower open ends of the tubes are' normally closed by a late 162 that is fixed in cposition upon the uwer arm of the U-shape holder 159 below the ends of the tubes. This-plate is preferably glass so that the points of the needles resting and moving thereon will not be injured. At one point the late is provided with an orifice 163 (see igs. 8 and 14), and suitable means are provided for rotating the needle magazine to bring the tubes`156 successively in line withv the orifice 163. For this purpose the lower disk 157 is provided with a series of radialy pins 164 and the horizontal portion 129 of the shifter rod o is provided with a pivoted dog 165 that is arranged to project upwardly through a slot 166 in the horizontal plate portion 148. This dog is held by a spring 167 (see Fig.` 5) against the end of the slot 166 and the dog is curved or cam-shaped so that when the shifter rod fv is lifted the vend of the dog will`be projected against one of the pins 164 to turn the needleniaga'zine` one step. A holdin pawl 168 is preferably formed of a curve leaf s ring secured at oneend to the lower end o the upright portion of the magazine holder 159. The free end of the holding pawl 168 is V`-shaped and projects between the lower ends of two of the tubes 156 and accurately holds the magazine in position with one of the tubes-in line with the orifice 163 in the plate 162. When a tube is brought in line with the orifice,4 the lowermost pin therein will drop through into an' inclined tube or guide-Way 169 (see Figs. 87 9 and 10) that is carried by the reproducer arm on the rear face of the sound box, the upper end of which is preferably expanded or hopper like. A stop device in the form of a bent spring 170 (see Fi s. 13 and 14) is fixed at one end to the uprig t portion of the magazine holder 159; The needle holding tubes 156 of the magazine are provided some. distance above their lower ends with transverse slots 171 and the free end" of the stop spring`170 is arranged to project within the slot of the tube over the orifice 163 and engage the second needle therein so that only one needle will fall throu h the orifice 163 when the tube 1s broug t in line therewith. As soon as the tube passes beyond the end of the stop device, the needles therein will drop down but will be arrested by the glass plate 162. In this way the needles may be fed one at a time .at each operation of the machine. Holder 159 of the needle magazine is referably removable through an opening (indicated in dotted lines in Fig. 1) in the top of the machine casing, so that the magazine may be refilled with needles from time to time. This particular form of magazine however, will hold a very large number of needles that will be, accurately fed, one at a time as the machine is operated, and, as is well known, it is@ highly desirable to change the needle at each operation of the machine.

The guide tube 169 is arranged in line with an inclined orifice 172 in the needle holder 26 that opens into the central bore thereof just below the shoulder 144 (see Fig. 1U). As the reproducer arm and sound box are lifted by the vertical movement of the shift rod a and rail W, the end of the pin 145, as stated, will be guided in the V-shaped cam slot 152. The tail of the clamp will be brought against the cam 153, and as soon as the sound box is partially lifted or about in the position indicated in dotted lines in Fig. 11, the old needle will drop from the holder 26. As the sound boi approaches the upper end of its movement, it will be shifted by the engagement of the cam groove with the pin 145 thereof to bring the needle holder over the end of the hookshaped abutment or stop 154. At this point, and while the clamp 140 is still held in released position by the cam 153, the dog 165 on the shifter rod fu will turn the needle magazine so that a new needle will drop therefrom through the guide tube 169 and guide o ening 172 into the central bore of the nee le holder 26. It will not fall out of the same but will be arrested in position within the holder by the abutment or stop 154. At the end of the upward movement of the sound box the tail of the clamp 140 will pass over the upper end of the cam 153 and the spring 143 will shift it to grip and hold the new needle. At the same time, the pin 145 on the sound box escapes from the upper end of the cam slot 152 and the sound box and reproducer arm slide down the then inclined rail W to the outer periphery of the disk on the turn-table.

To insure that the reproducer arm will always be brought to rest in such position that the pin 145 will engage the lide groove 152 when the sound box is lifted, the several disks, the record portion of which frequently vary in length, are provided with spiral grooves 173 (see Fig. 2) leading inwardly from theend of the record ortionto a circular groove 174 which is so ocated that it will hold the pin 145 on the` end of the reproducer arm a ainst the cam plate 146. To guide the nee le into the beginning of the record groove the disks are also preferably provided with spiral grooves 175 leading inwardly from the edge thereof to the beginning of the record groove.

The operation is as followsLThe sound box and reproducer arm are normally at their innermost end of their table with pin 145 thereon in engagement with the lower end of the cam late 146 and the record previously repro uced is on the turn-table C. In this position, the pin 46 on the chain 44 holds the arm 47 elevated so that the governor arm 40 is held in engagement with the disk 37 to prevent the operation of the turn-table, and the lug 66 onthe lever 60 is held in its uppermost position so that a coin may be dropped to position upon the lug 64 of the lever arm 61. In this position too, the disk record magazine or holder from which one of the records has been removed (in this instance thefmagazine at the right of the machine casing when viewed from the front) is locked against movement but the magazine at the left may be shifted if desired, by means of a button 87 on the front of the machine casing to bring any one of the disks between the arms at the left hand end of the disk shifter or carriage. If a coin is dropped into the chute 62 it will be arrested upon the lug 64 of the lever 61. The user may then turn the shaft F by means of the exterior handle f. The first initial movement of the shaft and ratchet wheel 50 thereon will as described, through the medium of the lever arms 67, 60 and 61 and rod 73'lift the locking pawl 55 out of the notch 54 of the ratchet 50 so that the shaft F may be turned and the dog 51 brought in line with the lug 53 on the sprocket wheel 45. The shaft F may then be turned through a single revolution or un til the locking pawl a ain engages the notch 54. The spring d o the turn-table motor is wound up as described, through the medium of the chain 44 and sprocket wheel 43 on the motor shaft. Pin 46 on the chain is drawn from beneath the lever arm 47 so that the governor arm drops out of engagement with the disk 37 and so that the lug 66 on the lever arm 60 is lowered into midposition in the coin chute to prevent the operation of the machine by another coin until the initiated operation is completed. 'Ihe reengagement of the locking pawl 55 with thel notch 54 of disk 50 throws the dog 51 out of engagement with the lug 53 on the ratchet w eel 45 so' that the spring d may turn the parts connected thereto in opposite direction to drive the turn-table. As the shaft F is rotated the cam 108 thereon lifts the arm P, energizes the motor s ring p and lifts the stop bar S thus shi ting the dog s thereon to free the shaft 102 and permit the operation of the automatic mechanism for changing the record disks and needle and restoring the reproducer arm. This shift of the stop device S also, as described, brings the button on its spring arm 122 against the lower disk of the governor and it is held in this position by the engagement of the pawl s' wlth the circular rib 119 until the shifter mechanism has changed the lates and moved the reproducer arm. Vhen the in 107 on the arm P passes over the shoul er of the cam 108, the motor spring p is thrown into operation 'to turn he sha t 102 through a half-revolution and urn the shifter cam 132 ythrough a single revolution. As stated, the lower end of the shifter rod 'v is pointed or V-shaped and sets within a correspondingly shaped notch in the cam 132. By reason of this arrangement, the instant the motor spring p is thrown into operation the centering device on the shifter rod u is quickly lifted to release the disk on the turn-table. The continued movement of the shaft 102 through its half-revolution moves are arm N and carriage M to change the plates, and at the end o lits movement to one side the tooth t on the arm 103 of the shaft engages one of the wheels T to automatically shift the disk magazine on that side one step. The movement of the shifter arm N, as stated, also automatically locks the magazine from which the record is taken and unlocks the magazine on the other side into which the disk on the table is moved by the' shift of the lu 128 on the arm N from beneath the pin 12 on one pawl t and by its rengagement with the pinon the other pawl. The movement of the motor shaft 102 as stated, isarrested after a half-revolution by the engagement'of the dog or pawl s on the stop bar S with the notch in the rib 119 of the gear 111 on' the shaft. After the first quick initial shift of the 4rod u, the continued movement of the cam 132 lifts this rod more slowly to raise the reproducer arm and sound box through the medium of the track bar W, and to turn the needle magazine through the medium of the dog or pawl 165. The reproducer arm is guided as described, during its upward shift by the engagement of the pin 145 thereon with the V-shaped cam slot 152 and the clamp 140 is shifted by its engagement with the stationary cam 153 to release the used needle and grip the new needle from the magazine that is guided into the needle holder 26 by the tube 169. Near the end of the movement of the cam 132 the shifter rod is in its uppermost position and the reproducer arm upon the turn-table and also to lower the sound box and needle on the reproducer arm into engagement with the disk. The centering device V is, as previously described, provided with a conical roller on its lower end, which, when the centering device is lowered, is arranged to engage the central opening of the record and thereby accurately center the record on the turntable, or, in other words, move or adjust it to proper central position thereon. In this way the shifted record is accurately centered or 4'adjusted to proper position on the turn-table, and, at the same time, it is moved out of contact with the parts of the sliding carriage or record shifter, so that the latter, as shown in Fig. '2, does not contact with the record on the turn-table during the reproduction thereof. By means of the depressions 121 on rib 119, the stop device 123 will release the governor of the turntable motor just before the needle is lowered into engagement with the disk on the turn-table so that the latter acquires a slight impetus before it is engaged by the needle. The turn-table, together with the disk thereon, are then rotated by the operating motor therefor, and the needle is guided by the spiral groove 175 into the beginning of the record groove of the disk. The reproducer arm and sound box are then swung inwardly as the needle passes through the record groove in the well-known manner to reproduce the same. It will be noted that as soon as the shaft F has been turned through a slight arc, the pawl 55 will engage the ratchetteeth of disk 50 and the winding shaft cannot be returned to its initial position, but must be rotated forwardly through a complete revolution before the actuating mechanism can be released into operation. In this way, the user is compelled to wind upV the motor spring sufficiently to completely reproduce the record on the turn-table. Moreover, while the record is being reproduced the lug 66 on the arm 60 is lowered in the coin chute so that another coin cannot be inserted to release the winding shaft. At the end of its movement, the sound box will be shifted by the engagement of the needle with the spiral groove 178 until the pin 145 engages the lower end of the cam plate 146. The pin 46 on the chain'44 will then rengage the arm 47, lift the governor arm 40 to stop the operation of the turn-table motor and shift the lugs 66 to its uppermost position out of the center of the com slot so that the machine is ready for the next operation.

It is obvious that numerous changes may
